Police in Pasco, Washington, have shot and killed four people in the past seven months, calling into question whether there’s a pattern of use of excessive force by the police department in the city of 68,000 population.

Police officers gunned down Antonio Zambrano-Montes, 35, last week, drawing attention to the rash of shootings that have occurred since July. Zambrano-Montes was being pursued by police for throwing rocks at passing cars. The shooting was captured on video. Since the shooting, community members have staged rallies to protest Zambrano-Montes’ death.

Pasco’s population is 56% Hispanic, but only 14 of the 68 officers are Hispanic. The city council has one Latino member, and the five-member school board has no Latinos.

The other shootings incidents since July, according to TheSeattle Times, were:

Rick R. Howard, 49, on July 9 who was fatally shot by a regional SWAT team during a four-hour standoff in Pasco. Howard was drunk and suicidal while firing a rifle at officers.

Brad D. Jensen, 34, on July 29, who was shot multiple times by two Pasco officers after refusing to drop a knife. Jensen was the son of a former Pasco police detective and city councilman.

Matthew L. Stoddard, 25, on September 24, who was shot and killed after pointing an Airsoft pistol, which fires BBs at an officer. He had led police on a short chase while driving a stolen car before the shooting.
